Study Notes

Information Systems

Composed of five components: people, procedures, software, hardware, and data.
People are the end users who interact with the system to enhance productivity.
Procedures include rules and guidelines for using software and hardware effectively.
Software refers to the programs that convert raw data into meaningful information.
Hardware encompasses the physical devices used in the information system.
Data consists of unprocessed facts awaiting processing for usability.

Data vs. Information

Data consists of raw, unprocessed facts; for example, customer purchase records.
Information is data that has been processed and organized to provide meaning.

Operating System

An operating system is essential software that manages computer hardware and software resources.
It facilitates communication between applications and the hardware.
Examples include Windows, macOS, Linux, and Unix.

Application Software

Application software serves specific user needs and tasks, often termed "end-user" software.
Common examples: word processing (MS Word), spreadsheets (Excel), databases (MS Access), and presentations (PowerPoint).

Types of Application Software

Basic applications are essential for everyday computer usage.
Specialized applications cater to particular tasks in fields like multimedia and education.

Input Devices

Input devices allow users to interact with computers by converting user actions into a form the computer can process.
Common examples include keyboards and mice. Other devices include scanners, microphones, and digital cameras.

Output Devices

Common output devices include monitors, printers, speakers, plotters, and projection units that display or produce results from computer processes.

Storage Types

Primary storage (e.g., RAM) is temporary and loses data when power is off.
Secondary storage (e.g., hard drives) retains data even when power is turned off, providing long-term data storage.

Internet vs. World Wide Web

The Internet is a vast network of interconnected computers and devices, forming the foundation for data communication.
The World Wide Web is a collection of multimedia resources accessible over the Internet, representing one of many Internet applications.

Types of Computers

Supercomputers are the most powerful computers used for complex calculations and large-scale processing requirements.
Mainframes offer high processing speeds and storage but are less powerful than supercomputers.
Minicomputers are midrange systems suited for specific tasks, typically used by medium-sized businesses.
Microcomputers, despite being the least powerful, are the most widely used type of computer for personal and small business applications.

URL Components

Uniform Resource Locator (URL) parts include the protocol, domain name, and file path, defining the resource location on the Internet.
